Description

Technical Field

[0001] The present invention relates to the technical field of die-casting molds, and specifically to a die-casting mold for die-cast parts of communication products that can reduce air holes in the castings. Background Technique

[0002] A die-casting mold is a tool for manufacturing metal parts, usually composed of a fixed mold and a movable mold. By applying a huge external pressure, the two molds are closely fitted, and then molten metal liquid is poured into the mold, so that the metal liquid fills the cavity inside the mold and is demolded after cooling and solidifying. Many parts in communication products are made by die-casting, such as the casings of mobile phones or tablets, and some special-shaped parts inside. However, there are still some problems in the use of existing die-casting molds, which are specifically as follows:

[0003] Existing die-casting molds need to perform exhaust and air extraction operations before die-casting to avoid air remaining in the cavity inside the mold, which may cause air holes in the subsequent formed parts, thereby reducing the quality of the parts. And the existing mold air extraction is to extract air from one end while squeezing the molten metal solution into the cavity at the same time at the other end, which may cause air to be mixed into the solution during the squeezing process. At the same time, the air outlet holes of the gas are all set at the top of the mold and cannot be discharged from other parts of the mold in time, resulting in too long travel distance and time of the gas in the cavity, greatly reducing the use efficiency of the mold, and also not being able to well reduce the occurrence of air holes in the parts after production. And the functions of each component of the existing mold are relatively independent, which increases the overall complexity of the mold. At the same time, the cooling of the mold cannot well approach the internal parts, resulting in a more sufficient and long heat conduction during the cooling process, which reduces the die-casting forming time of the parts. For this reason, we propose a die-casting mold for die-cast parts of communication products that can reduce air holes in the castings. Summary of the Invention

[0018] 1. The die-casting mold for the communication product die-casting part that can reduce the air holes in the casting. By arranging cooling air channels inside the fixed die, and at the same time, a multifunctional component is embedded and installed on the fixed die. The circular holes opened at the embedding position of the multifunctional component are in communication with the cooling air channels.

When the driving component drives the multi-functional component, the multi-functional component can be extended from the fixed mold into the cavity to eject the part. When the shrinking end of the multi-functional component is flush with the cavity, the closed space is injected with solution, and cooling and cooling molding is performed after the injection molding stage is completed. When the multi-functional component shrinks to the inside of the inner chamber, gas is injected between the part and the cavity to assist in demolding. At the same time, the negative pressure channel is opened when the multi-functional component enters the cavity, thereby realizing a rapid vacuum operation after the demolding mold is closed to ensure that the solution can be quickly injected later. When the driving component drives the degassing component, the rapid rotation of the driving component is used to make the degassing component oscillate at a high speed, so that the degassing component hits the mold at a high frequency after the solution is injected into the cavity, so that all the bubbles in it can move up and be discharged from the top, greatly reducing the existence of pores.

Detailed implementation manners

[0031] The following will clearly and completely describe the technical solutions in the present invention in conjunction with the accompanying drawings. In addition, the forms of each structure described in the following embodiments are merely examples. The die-casting mold for communication product die-castings that can reduce the air holes in the castings involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0032] Please refer to Figures 1-5 , a die-casting mold for communication product die-castings that can reduce the air holes in the castings, including a fixed mold 1. Outer channels 2 are opened at the upper and lower ends on one side of the fixed mold 1. An inner cavity 3 is opened inside the fixed mold 1. A cooling air duct 4 is opened inside the fixed mold 1. A top cover 5 is fixedly installed at the top of the fixed mold 1. A multi-functional component 6 is movably installed inside the inner cavity 3. A degassing component 7 is fixedly installed inside the inner cavity 3. One end of the multi-functional component 6 is fixedly installed with an air guiding component 8. A driving component 9 is fixedly installed inside the inner cavity 3;

[0033] In this embodiment, it should be noted that by providing a cooling air passage 4 inside the fixed mold 1, and a multi-functional component 6 is also embedded and installed on the fixed mold 1. A round hole is provided at the position where the multi-functional component 6 is embedded and is in communication with the cooling air passage 4. In this way, the gas injected through the multi-functional component 6 can enter the inside of the cooling air passage 4. The distance between the inside of the cooling air passage 4 and the cavity is very small, which can greatly increase the cooling and temperature reduction forming rate compared with the traditional cooling method. In this way, the production efficiency of parts can be increased, and the gas ejected from the end of the multi-functional component 6 can also help the part to be demolded to a certain extent and ensure the demolding effect. At the same time, a driving component 9 is provided inside the fixed mold 1. The driving component 9 can cause its two ends to contract to achieve contact control of the multi-functional component 6 or the degassing component 7. When the driving component 9 drives the multi-functional component 6, when the multi-functional component 6 extends out of the fixed mold 1 and enters the cavity, it can eject the part for demolding. When the end of the multi-functional component 6 contracts to be flush with the cavity, it is a closed space for injecting the solution, and cooling and temperature reduction forming are carried out during the injection molding stage. When the multi-functional component 6 contracts into the inner cavity 3, gas is injected between the part and the cavity to assist in demolding. At the same time, when the multi-functional component 6 enters the cavity, it will also open the negative pressure channel, and then a rapid vacuum pumping operation is carried out after the demolding mold is closed to ensure that the solution can be injected quickly subsequently. When the driving component 9 drives the degassing component 7, the rapid rotation of the driving component 9 will cause the degassing component 7 to oscillate at a high speed, so that the degassing component 7 hits the mold at a high frequency after the solution is injected into the cavity, so that all the bubbles in it can move up and be discharged from the top, greatly reducing the presence of air holes.

[0034] Please refer to Figures 1-4 , a die-casting mold for die-cast parts of a communication product that can reduce air holes in the casting, including a fixed mold 1. An embedded groove is provided on one side of the fixed mold 1 where the cavity is located. The embedded groove is in communication with the cooling air passage 4. The cooling air passage 4 is provided inside the fixed mold 1 between the cavity and the inner cavity 3. The cooling air passage 4 is in communication with each embedded groove and the top of the cooling air passage 4 penetrates the top of the fixed mold 1;

[0035] In this embodiment, it should be noted that in this way, the gas can be directly discharged into the inside of the cooling air passage 4 for flow after passing through the multi-functional component 6. Since the cooling air passage 4 is relatively closer to the cavity, the heat of the part can be better driven out by the flow of the gas to increase the cooling effect and improve the production efficiency of the part.

[0036] Please refer to Figures 3-7, a die-casting mold for a communication product die-casting part that can reduce air holes in the casting, including a multi-functional component 6. The multi-functional component 6 is movably installed by being embedded in an inner embedded groove on the fixed mold 1. A de-bubbling component 7 is sleeved on the multi-functional component 6 and is movably arranged. One end of the de-bubbling component 7 is fixedly installed inside the inner cavity 3. The driving component 9 can be separated from the multi-functional component 6 and the de-bubbling component 7;

[0037] In this embodiment, it should be noted that in this way, the driving component 9 can be used to drive the de-bubbling component 7 to continuously knock on the fixed mold 1 when air bubbles need to be removed. This can enable the air bubbles in the solution just injected into the cavity to move upward better in the solution, facilitating the discharge of air bubbles, and further ensuring that the air holes in the subsequent pressed parts can be greatly reduced, improving the quality of the product.

[0038] Please refer to Figures 1-7 , a die-casting mold for a communication product die-casting part that can reduce air holes in the casting, including a multi-functional component 6. The multi-functional component 6 includes a base frame 61. One side of the base frame 61 is fixedly installed with an extension pipe 62. An air outlet groove 63 is opened at the end of the extension pipe 62. A limit end block 64 is fixedly installed on the extension pipe 62. A toothed plate 65 is fixedly installed on the extension pipe 62;

[0039] In this embodiment, it should be noted that the inside of the base frame 61 is hollow. The extension pipe 62 is slidably arranged by fitting the inner embedded groove on the fixed mold 1. The toothed plate 65 is arranged on both sides of the central extension pipe 62. The size of the opened air outlet groove 63 is the same as and corresponds to the size of the cooling air duct 4. The limit end block 64 restricts the sliding arrangement of the de-bubbling component 7. In this way, when the multi-functional component 6 needs to extend into the cavity, it can reflect the function of ejecting and demolding the part. When the base frame 61 shrinks and is flush with the inner embedded groove of the fixed mold 1, it can ensure that the internal molten metal can be formed intact, ensuring the integrity of the part shape. When the base frame 61 shrinks into the inner cavity 3, the gas can be used to further cool and shape the basically formed part, and it can also assist in the preliminary demolding operation to ensure subsequent complete demolding.

[0040] Please refer to Figures 6-10 , a die-casting mold for a communication product die-casting part that can reduce air holes in the casting, including a de-bubbling component 7. The de-bubbling component 7 includes a support rod 71. A collar 72 is fixedly installed on the support rod 71. One side of the collar 72 is fixedly installed with a telescopic rod 73. A spring 74 is fixedly installed on the collar 72. A contact block 75 is fixedly installed on one side of the support rod 71;

[0041] In this embodiment, it should be noted that the collar 72 is slidably sleeved on the extension pipe 62. Both ends of the telescopic rod 73 are fixedly connected to the inner cavity 3 and one side of the collar 72 respectively. The spring 74 is sleeved outside the telescopic rod 73. The touch block 75 is installed outside the driving component 9. After the molten metal is injected into the cavity of the fixed mold 1, the driving component 9 can be used to continuously and reciprocally push the touch block 75 during rotation, so that the telescopic rod 73 continuously contracts and impacts and vibrates. This can make the bubbles in the molten metal flow upward better to ensure the elimination of bubbles, thereby reducing the presence of air holes in the casting.

[0042] Please refer to Figures 5-8 , a die-casting mold for a communication product die-casting part that can reduce air holes in the casting, including an air guiding component 8. The air guiding component 8 includes a connecting pipe 81. One end of the connecting pipe 81 is fixedly installed with a riser pipe 82. The top end of the riser pipe 82 is fixedly installed with a partition plate 83. One side of the partition plate 83 is fixedly installed with a first support rod 84. The other side of the partition plate 83 is movably installed with a second support rod 85. Both sides of the top end of the riser pipe 82 are fixedly installed with flexible hoses 86. One end of the flexible hose 86 is fixedly installed with a side bin 87. Inside the side bin 87, a first baffle plate 88 and a second baffle plate 89 are movably installed. The top end of the side bin 87 is fixedly installed with an outer air guide pipe 810;

[0043] In this embodiment, it should be noted that the connecting pipe 81 is connected to the base frame 61 in a penetrating manner. The length of the partition plate 83 is greater than the opening height of the side bin 87. The second support rod 85 is hinged to one side of the partition plate 83. The other side of the second support rod 85 is hinged to the second baffle plate 89. The other end of the first support rod 84 is detachably arranged with the first baffle plate 88. Both sides of the two side bins 87 are fixedly connected to the inside of the inner cavity 3. The flexible hose 86 is hermetically fixedly connected to the top end of the riser pipe 82 and the side bin 87. The first baffle plate 88 and the second baffle plate 89 are arranged to open and close alternately. The outer air guide pipe 810 is hermetically connected to the air supply device and the negative pressure suction device in a penetrating manner. The first baffle plate 88 is connected to one end of the air supply device in a penetrating manner. The second baffle plate 89 is connected to one end of the negative pressure suction device in a penetrating manner. When air supply is required, the driving component 9 is used to drive the multifunctional component 6 to move, so that the riser pipe 82 moves towards the side of the first baffle plate 88, opening the channel where the first baffle plate 88 is located. At the same time, the second baffle plate 89 will be pulled to close. In this way, the externally supplied gas will flow downward under the action of the partition plate 83 and enter the connecting pipe 81, thus realizing the air supply operation. When vacuum pumping is required, the driving component 9 is used to drive it to move in the reverse direction, opening the second baffle plate 89 while automatically closing the first baffle plate 88. And because it is a vacuum pumping action, the first baffle plate 88 will not open under the action of negative pressure adsorption, ensuring the airtightness inside.

[0044] Please refer to Figures 9-10, a die-casting mold for die-cast parts of a communication product that can reduce air holes in the casting, including a driving component 9. The driving component 9 includes a bracket 91. One end of the bracket 91 is fixedly installed with an electric telescopic rod 92. The end of the electric telescopic rod 92 is fixedly installed with a bracket 93. A driving motor 94 is sleeved on the bracket 93. A driving wheel 95 is fixedly installed on the output shaft of the driving motor 94. A convex plate 96 is fixedly installed on the side of the driving wheel 95. A toothed ring 97 is arranged on the side of the driving wheel 95;

[0045] In this embodiment, it should be noted that the bracket 91 is fixedly installed inside the inner cavity 3. The convex plate 96 can be in contact with the touch block 75. The rotation direction of the driving wheel 95 is from the middle direction of the position where the bracket 91 is located to both sides. The driving motor 94 is a stepless motor. The convex plate 96 is composed of upper and lower parts. The toothed ring 97 is located between the upper and lower convex plates 96 and meshes with the toothed plate 65. The thickness of the toothed plate 65 is less than the distance between the upper and lower convex plates 96. When it is necessary to adjust and control the lateral movement of the multifunctional component 6, the electric telescopic rod 92 can be contracted so that both toothed rings 97 are engaged with the toothed plate 65. In this way, the driving of the multifunctional component 6 can be realized by the speed regulation rotation of the driving motor 94. When it is necessary to eliminate the bubbles in the injected molten metal, the electric telescopic rod 92 can be extended so that the toothed rings 97 on both sides are separated from the toothed plate 65, and at the same time, the rotation range of the convex plate 96 reaches the position where the touch block 75 is located. By adjusting the speed of the driving motor 94, the degassing component 7 can continuously vibrate the fixed mold 1, so that the bubbles in the metal solution can flow upward better and be discharged, reducing the air holes in the subsequent casting.

[0046] Working principle: tightly fit the fixed mold 1 with the moving mold. First, contract the electric telescopic rod 92 so that the tooth ring 97 meshes with the tooth plate 65. Start the driving motor 94 to drive the extension pipe 62 to move into the cavity of the mold. At this time, the base frame 61 will drive the riser pipe 82 to move towards the second baffle 89, thereby opening the channel where the second baffle 89 is located. Use an external negative pressure suction device to exhaust and evacuate the inside of the cavity. Then, contract the extension pipe 62 until it is flush with the inside of the cavity. The high-pressure liquid supply device pours the molten metal solution into the cavity. At this time, extend the electric telescopic rod 92 so that the convex plate 96 moves to the area where the touch block 75 is located. Rotate the driving motor 94 to continuously squeeze and push the touch block 75 to move, thereby compressing the spring 74. At the same time, it will also cause the telescopic rod 73 to continuously collide and generate vibrations, so that the bubbles in the metal solution can flow upward better and be discharged. At the same time, the external air supply device will supply air into the connecting pipe 81 from the side where the first baffle 88 is located. Then, the gas is discharged from the air outlet groove 63 through the extension pipe 62 and enters the cooling air duct 4. In this way, the gas can fully flow along the back of the casting to take away the heat for heat dissipation and cooling to form. After basic forming, the tooth ring 97 rotates again to drive the multi-functional component 6 to contract into the inner cavity 3. After the end of the base frame 61 moves to a position where the inner cavity 3 communicates with the inside of the cavity, stop. At this time, continuously supply gas for direct contact cooling, and the pressure of the gas will also generate an initial demolding force. After cooling is completed, open the moving mold, and the driving wheel 95 rotates in the reverse direction again to drive the base frame 61 to move into the cavity, thereby ejecting and demolding the casting from the cavity.
